TO .ALL WHOMlT MAY CONCERN: r I

Be it known that I, E. Z. WEBSTBR, of "Louisville, in the county of Jefi'erson, and in the Stateo'f Kentucky,

have invented an Improvement inHeatingApparatus for Cars, Buildings, 860.; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to theaccouipan ying drawings, making a part of this specification, in which- Figure lis a side elevation. I

; Figure 2 is a perpendicular longitudinal section.

Figure 3 is a view of the heater, with the top plate removed. v

Figure 4 is a view of the bottom the heater, with the lower plate and ash-pan removed.

Figure 5.is a horizontal section of figs; 1 and 2, at the intersection of the line y y.

Letters of like name refer to like parts in each of the figures. a v i i I v A represents the cylinder, enclosing the fire-pot B, between which suificient space is left-to serve as a returnflue, Q, through which the smoke passes into the smoke-flue D, as shown by the red arrows.

E represents the grate, and F the ash-box, through which air is admitted to the fire. by the inilve a H represents a casing, which completely encloses-thefurnace, and forms a chamber 'for heating the air, which is admitted through the valve I, passes over the top of the furnace, and through thehot air flue K, and registers, L, into the car, as shown by the black arrows.

. M represents a slide, opening into a hopper, N, at the bottom of which is placed another slide, 0,.that opensinto the cylinder, A-, for the purp'oseof supplying fuel to the furnace. I P represents a damper, of the usual form, placed inthe smoke-flue to assist in regulating the draught.

The valves G and .I-are so constructed that they can be set to admit the air from the direction in which the caris mo\'ing. By opening them, so that the edge toward thefront end of the car is presented obliquely, the air is caught and forced into the furnace or heater, producing as strong current as is'dcsired. I

'Thc-s-mokc-fluc D passes through the hot-air flue K, which serves as a jacket, by which means all heat that would otherwise be carried into the open air with the smoke and wasted, is saved and used for warming the ear.

The bottom of the heater extends far enough below the floor Rlt'o al'lhw the smoke and hot-air fines to pass beneath .it..

The furnace, grate, .&c., maybe eonstrjucted ofcast iron,-butthe cnsingmust be made of boiler-iron,

strongly bolted together, to enable it to withst and any force that might otherwise crush it in. case of-a collision,

thereby avoiding danger to the car from fire..

The operation ofthis heatcr'is as follows, viz:

The 'vaive G and-damper P are opened, and fire started upon the grate in the usual manner; after which the valve I is opened, so as to catch the air which is forced into the hot-airchamber between the casing H and furnace A, \Vllelffltdt is heated, andpasses through the flue K and registers L into the car;

When it is necessary to supply fresh fuel to the furnace, the slide M is opened, and the hopper N filled with coal, and the slide closed. 'By'opening the slide'O the coalnow falls into the cylinder A, without allowing the escape of gas or smoke. v

- The advantages possessed by this heater over all others in use, are- I First, entire safety from fire; The furnace is completely enclosed in thecasing', which, being made of boiler iron, strongly bolted together,- iscapable of withstanding the severest shock during a collision, or when a car 4 is. thrown from the track, without sustaining sufiicient injury to allow the fire to escape. I

v Second, economy. By enasing the smoke-flue Within the'hot-air flue, the heat that passes oii' with the smoke is saved and used fonwarming the car, rendering less fuel necessary, and thereby reducing the cost. ;It also furnishes means for warming cars in a morelthorough mariner.

Third, convenience. The arrangement of the hopper N and slides M and 0 allows the furnace to be supplied with coal without theescap'eof gas or smoke, and, the ashes and refuse are taken out below the car,

thereby avoiding all annoyance from dust or ashes'within the ear.

This heater can also be used for warming buildings, in which case the casiiig coin be made of cast iron, and the entire heater placed above the floor, materially reducing the cost.

"Having thus fully set forth the nature and merits of my improvement, -what claim as my invention, and desire to secure by Letters Patent, is-

The slides M and O. iri combination with the hopperN for supplying coal to the fornnce, substantially aehereindescribed.

Also; the combinationof the furnace A, cesing H, valves 1 and G, smoke mil hot-air time D and K, slides M and Oymid hopper N," for the puitpbso, and substantially as herein specified.

"Inte'stimony that I claim the foregoing, I-have hereunto set my'hand, this 20th day of February,1868.
